BARCODE SCANNING DEVICE FOR CYLINDRICAL SECONDARY BATTERY

A barcode scanning device for a cylindrical secondary battery which scans a barcode positioned on a side surface of the cylindrical secondary battery, the barcode scanning device including: an illuminator configured to emit light; a barcode reader configured to scan a barcode by receiving the light; sub mirrors which include one sub mirror located relatively close to the barcode reader and another sub mirror located relatively close to the cylindrical secondary battery; and a main mirror configured to reflect, toward the barcode reader, the light which is reflected from the sub mirror located relatively close to the barcode reader. The sub mirror located close to the cylindrical secondary battery is located at a position capable of receiving the light reflected from the side surface of the cylindrical secondary battery, and reflects the received light to the sub mirror located close to the barcode reader.
